Our present car (2005 VW Touareg) is really uneconomical at about 22mpg on bio, even using 2EHN.
I was surprised to learn that a 2015 Skoda Octavia 1.6 TDI has a consumption of 45 to 60 mpg and the biggest benefit...........No TAX
This means that the fuel cost per month for DERV bearing in mind our small 200 mile journeys/monthly would be hardly any more expensive than running the Touareg on Bio.
So guess what, yes we bought the Octavia and the Touareg is going on jan 2nd. The monthly saving will be about the same as the monthly tax amount on the Touareg which is Nearly £37
But don't worry guys, I will still carry on making bio for my van and the central heating.
